STRAW STAGKER AND` ELEVATOR.

To all whom t may concern:

Be it known that LAUeUs'r RosnN'rrmL, residing in West Allis, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Straw Stackers and Elevators, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to improvements in straw stackers and elevators adapted for use with corn-huskers and shredding machines, threshing machines and ensilage cutters.

The principal object of this invention is to provide a stacker in which straw and fodder will be elevated and delivered from the stacker by oscillating and reciprocating means provided with engaging fingers.

A further object is to provide a jointed stacker tube and reciprocating means which may be folded without uncoupling any of the parts.

A further object is to provide a stacker tube with engaging fingers pivotally con nected thereto which are adapted to prevent retrograde movement of the material being elevated.

A further obj ect is to provide convenient means for folding the stacker. And a still further object is to provide means whereby the stacker may beswung or elevated to any angle desired without affecting the operation of the reciprocating bars.

With the above, and other objects, in view, the invention consists of the devices and parts, or their equivalents, as hereinafter set forth.

ln the accompanying drawings, in which the same reference characters designate the same parts in all of the views; Figure 1 is a side view of a portion of a threshing machine provided with the improved elevator and stacker, parts broken away, and the stacker being in longitudinal section; Fig. 2 is a plan view of the parts shown in Fig. 1; Fig. 3 is a cross sectional view of the stacker taken on line 3-3 of Fig. 1; Fig. 4E is a cross sectional view of the stacker taken on line 4-4 of Fig. 1; and Fig. 5 is a plan view of a modified form of stacker in which two reciprocating bars are shown. 4

Referring to the drawings, the numeral 8 indicates the discharge end of a threshing machine, and 9 the discharge outlet or spout thereof. Astacker supporting frame 10 pro- Specification of Letters Patent. Application led July 25, 1908.

jects rearwardly from said threshing machine and on this frame a stacker 11 is pivotally supported by means of a pivot pin 12 pivotally connected to said stacker and mounted in said supporting frame. llhis pivotal connection permits the stacker to be swung around and the outer end to be elevated to any desired position.

The stacker 11 is formed of an inner section 12 and an outer discharge section 13 connected together' by a hinge joint 14 and a gravity latch 15. A large sprocket wheel 16 is mounted fast to the outer section of the stacker and its shaft is in axial alinelnent with the hinge joint and forms the hinge pin of one portion of the hinge. A small sprocket wheel 17 mounted on the inner stacker section 12 and connected to the large sprocket wheel by a sprocket chain 18 is adapted to conveniently fold the outer stacker section upon the inner section with the application of but the minimum amount of power. The shaft of the small sprocket wheel is provided with acranked operating handle 19 and a ratchet wheel 20, and a pawl 20 pivoted to the inner stacker section is in engagement with the ratchet wheel.

The stacker, consisting of a straight section of tubing, merges into an enlarged lower end portion 21 provided with an opening 22 in the upper portion thereof and immediately beneath the discharge spout of the threshing machine. Y'lihe opening 22 of the stacker is so shaped and positioned with reference to its various positions of adjustment and the discharge spout of the threshing machine as to be always in proper position to receive the material discharged therefrom.

A cranked shaft 23 mounted on and extending transversely across the lower enlarged end of the stacker has connected thereto an oscillating bar 2a provided with engaging fingers 25 which are adapted to engage and elevate the material discharged into the lower end of the stacker. The upper end of this bar is curved upwardly and is pivotally -connected to the inner end of a reciprocating bar 26, also provided with engaging fingers .25, said bar and fingers serving to elevate and discharge the material moved into their path of movement by the fingers connected to the oscillating bar. The pin 27 connecting the two bars together extends transversely from the sides of said bars into slotted guidefways 28 connected to the upper end of the inner portion of the stacker. These guide-ways are so positioned with'relation to the hinge pin of the hinge joining the two sections of the stacker together that when the bars have been moved to their extreme outer position the pin 27 of said bar will be in axial alinement with the hinge pin of the stacker so that when in this position the stacker may be folded at the joint by means of the cranked lever and vsprocket wheels and chain without disconnecting any of the reciprocating parts of the stacker. The upper end of the reciprocating bar is supported and guided by means of a bolt 29 connected to said bar and passing through a slotted opening 30 provided in the outer stacker section, the nut of the bolt serving to support the bar vertically. Both sections of the stacker have a pair of stationary bars 3l also provided with engaging lingers 25 which are adapted to prevent retrograde movement of the material being elevated by the oscillating and reciprocating bars. The engagn ing fingers of these bars are pivotally connected thereto and are formed by inserting the wire, of which the fingers are formed, through openings provided thereforin the bars and bending said wire at right angles in the form of the letter U with the two stems positioned against the sides of the bars, the base of the U-shap`ed wire forming the pivotal connection with the bars. Stop pins 32 connected to the bars are positioned in the path of movement of the fingers to limit their swing so that in the forward reciprocation of the bars the fingers are permitted t-o swing to a position substantially at right angleswith Vthe bars and will be in position to engage and advance the material upwardly in the tube, and during the rearward reciprocation of the bars the fingers are permittedto swing toa position substantially parallel with the barsv and pass freely through the material so as not to obstruct or retard the progress of said material. The fingers connected to the sta tionary bars engage and hold the material during the rearward reciprocation of the reciprocating bars.

The cranked shaft 23 may be rotated in the ordinary manner by gears or belt wheels but a grooved wheel 82 and a rope 33 extending to a source of power rotation are shown as the preferred way of driving.

The stacker is swung on its pivotal connection with the threshing frame to elevate or lower the discharge end of the stacker by means of a small hand operated windless 33 mounted on top of the threshing machine and a rope or cable 34 connected at both ends to the shaft or drum of the windlass. The loop formed in the rope extends around the medial portion of the stacker and a small pulley connected thereto so that when the height of the stacker end is adjusted the stacker may be swung around horizontally in the arc of a circle without disturbing the position of adjustn'ient of the stacker end.

The gravity latch l5 is adapted to lock the two sections of the stacker together when in open or unfolded position.

A hinged member 35 connected to the threshing machine is adapted to guide the material into the stacker.

In the modified form of stacker shown in F ig. 5 a double crank 23 is provided and two oscillating bars 24 are connected thereto and are adapted to alternately oscillate in opposite directions. Reciprocating bars 31 are connected to the ends of the oscillating bar in the same manner as in the prin- .cipal form and are reciprocated thereby.

The other details of construction of this modified form are similar to the principal form with the exceptions that the two Sections of the stacker tube are hinged at a point midway between the two extreme positions of reciprocation of the bars so that when the double crank is at the half stroke position both pivot pins of the oscillating bars will be in axial alinement with each other and the hinge pin of the stacker and the stacker may then be folded without disconnecting any of the parts, and the guides 28 are in two parts overlapping at the hinge point and one part being connected to each section of the stacker.

The operation of the stacker is as follows: Material is fed to the stacker through the opening in the lower end thereof from the discharge spout of the machine to which it is connected. The material will be engaged by the fingers of the oscillating bar during its downward and forward stroke and moved upwardly into the path of movement of the reciprocating bar which will further move the material and finally discharge it from the discharge end of the stacker. The fingers of these bars will engage the mate` rial during the forward stroke and during the return stroke will swing against the sides of the bars and pass freely through the material, and during this return stroke the fingers of the stationary bars will prevent retrograde .movement of said material.

The stacker may be raised or lowered by means ofthe rope and windlass and may also swing around horizontally, and when it is desired to move the machine to which the stacker is connected from place to place the stacker may be folded by means of its hinged joint and reciprocating bars and the chain wheels.
